Feel it has to be 10:1 or above, so I'll go for broke and say #4 10.5:1 CR.

Nice try, however, answer #4 is not correct.:(

10.25:1 I believe.  It was the base Corvette 327/300 hp engine.  The 327/350 would have been higher.

That wouldn't be happy with today's fuel and no computerized engine management.
